Momentum meets PRO threshold (40+)
How Scoring Works:
Score = Quality × Confidence.
Quality (0-100) rates absolute performance across 5 dimensions:
Return-to-Risk (35pts), Total Return (25pts), Win Rate (15pts), Profit Factor (15pts), Consistency (10pts).
Confidence (100%) adjusts for trade count and freshness —
more trades + recent activity = higher confidence.
Momentum uses the same model recalibrated for a 30-day trailing window.
PRO status requires both Lifetime Score ≥ 70 and Momentum ≥ 40.

How to Read This Table
Each row is one complete trade cycle (BUY → HOLD → SELL). Professor Mean had $11,957.32 at period start. When he sees a buy signal, he uses all available cash to buy shares. He holds until hitting his +5% target, -10% stop loss, or 30-day limit. After selling, the profit/loss is added to his balance, and the next trade uses that new balance.
